A/B Testing WordPress Header

You finally have your blog up and running, filled with lots of great content, and ads to generate an income. But it’s not going as well as you hoped it would be.

Your articles aren’t getting enough views and shares on social media, no clicks on your ads, and people aren’t buying your products. Where did you go wrong? Is there a way to fix it?

Yes, there is! All those problems can be fixed with A/B Testing.

In this article, we’ll explain what A/B testing really is, what kind of benefits you can get from it, and we’ll also share some of the best tools for performing A/B tests on your WordPress blog with little or not money. So, grab a notepad and keep scrolling down.

What Is A/B Testing?

It may sound like a term used by researchers in a secret lab, but A/B testing, or split testing, is actually a simple process used by all marketers for increasing leads and sales.

However, it’s not limited to marketers either. Most website owners and bloggers are now using A/B testing to improve their website engagement and lead generation rates.

How does it work? Simply put, an A/B test is a process you can use to find what works best for your website or blog.

What is A/B Testing

For example, imagine that you have a landing page collecting emails from your website visitors. You can run an A/B test on your landing page by creating different versions of the page, each with different layouts, colors, and copy. Let’s call those two versions A and B.

Then you can split the traffic visiting the landing page and drive half of the traffic to the landing page A and the other half to landing page B.

After the testing period, you can evaluate which landing page generated the best results and then come to a conclusion on which design works better. It’s as easy as that.

Why Should You Care?

You might think that you have the perfect WordPress website since you spent a lot of money buying a highly rated theme from a marketplace. Folks over at Career Point College used to think the same way, that is until they ran an A/B test.

Apples to Oranges A/B Test

The results were huge. They managed to increase conversions by 336%, with a single A/B test that tested different layouts and design.

Having the right tools and high-quality content is no longer enough to generate effective results. You also need to test each element on your blog to find out which method can bring you the highest percentage of results.

Email Popup Test

Have a look at the email popup messages above. Which version do you think is most likely to collect the highest number of email signups?

Well, we don’t know for sure. The only way to figure it out is to run an A/B test.

What To Test?

A/B testing landing pages is only the beginning. There are so many things you can put to test on your WordPress blog. But, before we figure out how to do A/B testing in WordPress, let’s have a look at what kind of things you can split test to produce the best results.

  • Headlines: Test your article titles to get more people to read your posts, bring more traffic, and get more shares on social media.
  • Ad Placements: If you’re using any type of display advertising on your blog, like Adsense, you can run a split test to figure out the best areas for placing your ads to get more clicks.
  • List Builders: Get more people to sign up for your email newsletter by optimizing and split testing your popup messages.
  • Color and Design: Color has a strong psychological effect on our mind. Try changing the design and colors of your “buy” and “subscribe” buttons to increase conversions.
  • Call to Actions: Find the best place to insert your CTAs and get more engagement.
